Here We Go Again

I was going to pump it into the main hull. Through a gromet as was the power. That would be enough of an air leak to keep from blowing a seam. The reason I don't like out board hatch is because of the time I sunk one side of my catamaran. Something broke the port hull inspection plate and I was sideways before I found out.
By the way it was impossible for something to break that plate and it could never happen...LOL

I think you're finding an issue where none exists.

The increase in pressure from expansion of the air in a bracket from sitting in the sun just isn't that much.

As a corrallary, if you trailer a boat up to a high mountain lake, then the lower atmospheric pressure at altitude has the same net result as doubling the internal pressure where you started from.

You'll have to jet leaner, but nothing blows from the pressure differential.
